Permission denied in accessing file system in Linux/Unix

Have you ever experienced this message "Permission denied" when trying to access a file system in Unix/linux.


I have created lower level user eg: noci and I have given full permission to read the folder structure

eg :
drwxr-xr-- 11 root root 4096 Aug  4 13:23 Folder

folder owner is root, but i have given read access to all as you can see.

But when tried to access folder it gives me " Permission denied"  message.


Solution:
Give the execution permission. Without execution permission user cannot go inside folder structure.

turn off open new folder in a new window

In Linux you have a very bad experience. That is when you click a folder. it's content is open in a new window. This is pretty annoying. Below is the command to get rid of it. I have used and it works perfectly fine.
So how to execute command in Linux, If you don't know
just open an terminal and run below command

gconftool-2 -s '/apps/nautilus/preferences/always_use_browser' --type bool true
